WebSep 23, 2024 · Ribozymes, like protein enzymes, have a specified three-dimensional structure for catalytic activity. Ribozymes require metal ions such as K+ or Mg2+, which are naturally present in the cell, in order to fold. These ions counterbalance the large density of negative charges within a folded oligonucleotide. WebMost natural ribozymes catalyze nucleophilic reactions at phosphate centers to yield the ligation of two strands, phosphoester hydrolysis, or phosphoester exchange. Three powerful catalytic strategies used by natural ribozymes include specific positioning of substrates, incorporation of metal ions into active sites, and general acid-base catalysis.
